CD169 is a marker of IFN-γ-stimulated inflammatory macrophages in brain tumor [EGFRviii]

Project description:Therapies against glioblastoma multiforme (GBM) have been largely ineffective due to the infiltration of immunosuppressive tumor-associated macrophages (TAMs). Recent studies demonstrated that TAMs can also be immune-activating. However, markers differentiating these heterogeneous macrophage populations have not been established. In this study, we identified a subset of macrophages expressing CD169 that promote an anti-tumoral microenvironment in GBM. Using single-cell transcriptome analysis, we found that CD169+ macrophages in human and mouse gliomas produced proinflammatory chemokines, leading to the accumulation of T cells and NK cells. Depletion of CD169+ macrophages shortened the survival of mice with gliomas and reduced the function of antitumor lymphocytes. We show that IFN-γ produced by NK cells was critical for the accumulation of CD169+ macrophages into gliomas. Additionally, CD169 expression on macrophages increased the phagocytosis of apoptotic glioma cells. Our finding suggests that the CD169+ subset of TAMs promotes antitumor immune responses against GBM.

EGFRvIII/STAT3 targets in glioblastoma pathogenesis

Project description:Next generation sequencing platforms were used to identify STAT3 targets in the background of EGFRvIII expresssion mRNA of 3 EGFRvIII positive brain tumor stem cell lines (BTSC #68, 73, and 90) were compared to an EGFRvIII negative line (#41) to identify EGFRvIII-regulated targets in human BTSC. EGFRvIII-dependent targets in mouse astrocytes were identified by mRNA-seq analyses of EGFRvIII- or MSCV-expressing astrocytes. STAT3-differentially regulated genes in EGFRvIII expressing mouse astrocytes were obtained by subjecting EGFRvIII,STAT3f/f and EGFRvIII, STAT3-/- astrocytes to mRNA-Seq analyses. Sites of STAT3 occupancy in EGFRvIII expressing astrocytes were identified by ChIP-Seq using a STAT3 antibody or IgG control. We identified OSMR as a direct target of STAT3 in both EGFRvIII-expressing human BTSC and mouse astrocytes. Therefore to identify OSMR-regulated genes, we used a lentiviral mediated RNAi system to knockdown OSMR in EGFRvIII-expressing astrocytes. OSMR-dependent differentially expressed genes were obtained by comparison of OSMR knockdown (KD1 and KD2) astrocytes to control groups (ShRNA control and Vector control)

Transcriptional profiling of Cd169-lineage lymph node macrophages

Project description:Tingible body macrophages (TBMs) exist in lymph node B cell follicles and are responsible for clearing apoptotic B cells. Our data suggests that TBMs are of Cd169-lineage. We isolated cells from Cd169Cre/+.Tdtomatofl/fl reporter mice and transcriptionally profiled them to identify putative TBMs and chacterise their development and function relative to other LN cells of the Cd169 lineage.

Expression data from U87MG cells expressing EGFRvIII

Project description:EGFRvIII is the most common deletion mutant of EGFR in human cancer and its levels are highly correlated with poor prognosis in GBM. The deletion of exons 2-7 removes most of the extracellular ligand binding domain, so it is unable to bind EGF or other EGFR-binding ligands. Nevertheless, the mutant receptor is constitutively phosphorylated, and is capable of activating downstream signaling pathways at a low level. To comprehensively identify the downstream signaling consequences of the EGFRvIII, we incorporated phosphoproteomic, transcription profiling and DNase-Seq data from U87MG glioblastoma cells expressing titrated levels of this mutant receptor. Total RNA were extracted from U87MG cells engineered to expressed different levels of EGFRvIII: medium (U87M; 1.5 million copies of EGFRvIII receptor per cell), high (U87H; 2 million copies per cell), super-high (U87SH; 2.5 million copies per cell), and kinase-dead EGFRvIII (U87DK; 2 million copies of kinase dead EGFRvIII per cell). RNA was hybridized to Affymetrix microarrays.
